    C) Rs. 3000                       

    D) Rs. 3900

    Correct Answer: D

    Solution :

    Partners A B C
    Amount 40500 45000 60000
    Duration 6 12 6
    Amount 45000 45000
    Duration 6 6
    Ratio of capitals of A, B, C
    \[=(40500\times 6+45000\times 6):(45000\times 12)\]
    \[:(60000\times 6+45000\times 6)\]
    \[=(405+450):(450\times 2):(600+450)\]
                \[=855:900:1050\]
                \[=171:180:210=57:60:70\]
    Sum of ratio \[=57+60+70=187\]
    \[\therefore \] Required difference \[=\frac{70-57}{187}\times 56100\]
                            \[=\frac{13}{187}\times 56100=\text{Rs}\text{.}\,\,3900\]
